Date-relative information; seeking a better way.

[K1200]

I've implemented a TO-based method (see example file) for extracting date-relative information from a table. It works fine, but I'm thinking there must be a better way that doesn't require so much "infrastructure" -- or is this just a good use of FMP's features? It would be rather cumbersome to scale my approach upward, say to a 10-day period instead of four. Yet my application doesn't need a full-scale scheduling module. In fact, extracted days need to be viewed on different layouts (planning, materials, production, etc.), not as a master schedule.

Any thoughts and suggestions will be appreciated.

ALSO, can anyone tell me why the pop-up calendar in my example doesn't pop back down? These calendars seem to have a need to auto-tab to a next field and on this layout there's not one. I tried several things but an extra click out to the side is always required.
